UFC CEO Dana White announced multiple fights for UFC 320, taking place at T-Mobile Arena in Las Vegas. Ankalaev vs. Pereira 2 is the main event with Dvalishvili vs. Sandhagen serving as the chief support bout. White revealed a third fight for the event, a possible title eliminator between light heavyweights Jiri Prochazka and Khalil Rountree Jr.

Ateba Gautier seeks his third knockout victory of the year. Multiple people with knowledge of the promotion's plans confirmed to MMA Fighting that Gautier is set to return to face Ozzy Diaz at UFC 320.

Ankalaev will defend the light-heavyweight title he won against Pereira – at the same venue during UFC 313 in March – while the Brazilian will look to become champion of the division for the second time, after three previous successful defences of the title he won in late 2023.
